453 Dump Valve Adapter

This obviously only works on the turbo model of the 453, doesn’t matter if it’s manual or auto gear box.

It’s a spacer that sits between the turbo recirculation valve and the turbo body so when the recirc valve opens, it vents the pressurised air instead recirculating it back into the turbo inlet. You get the sweet (or annoying) PTSHHH noise. Plus it has been ported to the correct outlet size as per our previous Forge Motorsport dump valve design so enough pressure is kept to get you back on boost faster.

Photos of it fitted to the turbo can be seen here:
